This is the best one I've found
Here's a heads up... I was trying to order a new truss rod wrench and the Gibson 5/16 was out of stock at Stewmac. I found this one at Allparts for $6.49 and the cool thing about it is that it has a Philips screw driver on the other end for truss rod cover screws. Nice design.

Found a fun little track and just goofed around over the top of it.
